Access Node Resilience Using MC-LAG and Pseudowire
Redundancy (in Access-Uplink Mode)
Note: This section is applicable for 7210 SAS-M devices configured in access-uplink mode.
Note that MC-Lag and pseudowire redundancy are not supported on the 7210-SAS M OS (in
access-uplink mode), but the 7210 SAS D, E supports active/standby links which lets it to be dual-
homed to two PEs that support MC-LAG.
Figure 30 shows the use of both Multi-Chassis Link Aggregation (MC-LAG) in the access
network and pseudowire redundancy in the core network to provide a resilient end-to-end VLL
service to the customers. In the Figure 30, the 7210 SAS-M (network mode) can be used as the
aggregation node. The nodes represented by 7210 in the figure can be 7210 SAS-D or 7210 SAS-
E or 7210 SAS-M (access-uplink mode).
